IMPROVEMENT IN GAS-BURNERS.

Specification forming part of Letters Patent No. 194,63l, dated August 28, 1877; application filed November21, 1876.

To all whom it may concern.-

Be it known that we, JOSEPH D. WEST, of East Orange, in the county of Essex and State of New Jersey, and WILLIAM H. DARBY, of Brooklyn, in the county of Kings and State of New York, have invented a new and useful Improvement in Gas-Burners; and we do hereby declare that the following is a full, clear, and exact description thereof, reference being bad to the accompanying drawing making a part of this specification, in which- Figure l is a side elevation ot'our gas-burner; and Fig. 2 a central. vertical section of the same.

Like letters denote corresponding parts in each figure.

The object of our invention is to produce a simple and cheap device for heating and expanding the gas to the desired degree before it passes from the tip of the burner, and at the same time to heat and feed atmospheric air to the center of the flame, and assist in more thoroughly mingling the said air with the unconsumed carbon, thereby insuring a more perfect combustion of the gas, produc ing a brighter light and a great saving in the amount consumed.

Our invention therein consists in the construction and arrangement of the parts composing our improved burner to effect the above purpose, as fully hereinafter set forth.

In the annexed drawings, the base a, of the burner has the ordinaryinternal screw-thread, by which it is attached to the ends of the gaspipe in the usual manner. The upper end of the base is contracted in size to form a cap, a in which are made two oblique holes, a similar to the apertures in the tip of a fishtail burner. The shell b of the burner is a tube, fitted over the cap a of the base, and resting upon a shoulder, a This shell is either attached by screw-threads to the cap, or is sprung over the same. Ears 0 0 project up from the top of the shell, being formed in one piece therewith. These ears are made quite narrow, and bent inwardly close over the tip, with their upper ends 0 bent slightly outward, and enlarged, as shown. The tip 01 employed is a lava tip; but any other kind may be used without afiecting the operation of the other parts of the burner.

When our burner is in use, the gas passes with full pressure up through the base a till which throw the gas against the walls of the shell, bringing it into intimate contact with the same. It then rises to the tip (1 and is consumed. The ears 0 0 being almost in contact with the dark center of the flame, become highly heated, and conduct such heat to the shell b, which heats and expands to the desired degree the gas in the chamber f. These ears, by being narrow, and situated opposite the dark center of the flame, do not throw any shadow, or obstruct in the least the light or the passage of the air to the flame. On the contrary, by being so constructed, they assist to draw the atmospheric air; to the center of the flame, where it is most needed, and heat the air so that a more perfect combustion and a brighter light are obtained.

By heating and expanding the gas in the shell of the burner to a certain degree the same will combine more perfectly with the oxygen of the air, and a great saving in the amount of gas consumed will be the result.

The advantages of the means we employ to effect this result lie principally in their simplicity and cheapness, and in their efficiency in operation.

Having thus fully described our gas-burner, what we claim as new therein, and desire to secure by Letters Patent, is-

The gas-burner described, consisting of the base 0., having a cap, 00 provided with the oblique openings a the shell b, ears 0 c, and tip 01, constructed and arranged substantially as shown and set forth.
